After updating Xcode 14, I'm now unable to test my purchasing on my simulator using a configuration file (it says it is unable to connect to the App Store and fails to even bring up the purchasing sheet). I've downloaded Xcode 13.4.1 and keeping everything the same, am able to test purchasing successfully.

Can you file a feedback assistant ticket with appropriate logs, screenshots, app/IAP details? http://feedbackassistant.apple.com
